PEEK Right-Angle Compact Conductivity Sensor
The InstroDirect IDC-R90-PEEK PEEK Right-Angle Compact Conductivity Sensor — is a specialty right-angle PEEK-body conductivity probe for installations where a straight in-line probe won’t fit — narrow pipe runs, instrument panel bosses, OEM analyser cabinets, and laboratory bench rigs. RS485 Modbus / Pt1000, 0 – 20 mS/cm, IP68. Backed by Australian technical support, on-site calibration, and next-day Brisbane dispatch.
- Estimated delivery time 3-30 days - some items in stock in Australia
- 12 months standard warranty
- Genuine manufacturer-made products
Product details
PEEK Right-Angle Compact Conductivity Sensor — Tight-Space Installation
The InstroDirect IDC-R90-PEEK PEEK Right-Angle Compact Conductivity Sensor is a specialty right-angle PEEK-body conductivity probe for installations where a straight in-line probe won’t fit — narrow pipe runs, instrument panel bosses, OEM analyser cabinets, and laboratory bench rigs. The right-angle body lets you measure in a horizontal line while the cable exits vertically, saving 80 mm of vertical clearance.

Typical Australian Applications
- OEM analyser and datalogger integration
- Laboratory bench measurement rigs
- Compact instrument panels with limited clearance
- Small-bore sample lines (<15 mm ID)
- Flow cells in portable water-quality instruments
Why Integrators Choose the IDC-R90-PEEK
- Right-angle body saves ~80 mm vertical clearance over a straight probe
- 1/4″ NPT thread fits small-bore sample fittings and laboratory setups
- PEEK tolerates laboratory chemistries that would attack plastics
- Short form factor suits hand-held and portable instruments
- Low cost — ideal for OEM volume integration
Installation & Calibration Notes
Screw into a 1/4″ NPT port using PTFE tape. Ensure electrodes are fully submerged. Flying leads can be wired directly to a terminal block or a custom connector for OEM applications. Quote available for volume OEM builds.
Frequently Asked Questions
Can I order this in volume for OEM integration?
Yes. Minimum order quantity 10 units for OEM discount pricing. Branding options (private label, custom wire colours, custom cable lengths) available on request.
Why right-angle?
Some instrument panels don’t have the vertical clearance for a straight 100–150 mm probe plus cable entry. The right-angle geometry lets the probe measure in a horizontal line with the cable exiting vertically (or vice versa).
Is a 4-electrode version available?
Not in this right-angle form factor. For 4-electrode service choose IDC-4E-POM or IDC-4E-SS.
